CVE-2026-44369: CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) in cvat-ai cvat
CVAT is an open source interactive video and image annotation tool for computer vision. From 2.5.0 to 2.63.0, an attacker who is able to create or edit an annotation guide on a task is able to add malicious JavaScript code, which will then run in the browser of anyone who opens this annotation guide. This code will be able to make arbitrary requests to CVAT with the victim user's privileges. This vulnerability is fixed in 2.64.0.
AI Analysis
Technical Summary
The CVAT open source annotation tool has an XSS vulnerability (CWE-80) in versions 2.5.0 through 2.63.0. The flaw allows an attacker with limited privileges (ability to create or edit annotation guides) to inject malicious script code into annotation guides. When other users open these guides, the injected JavaScript runs in their browsers with their privileges, enabling unauthorized actions within CVAT. This vulnerability was addressed and fixed in version 2.64.0.
Potential Impact
Successful exploitation allows attackers to execute arbitrary JavaScript in the context of other users' browsers, potentially enabling unauthorized actions within CVAT using the victim's privileges. This can lead to unauthorized data access or manipulation within the application. There are no known exploits in the wild as of the published date.
Mitigation Recommendations
Upgrade CVAT to version 2.64.0 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are documented. Users should apply this update promptly to prevent exploitation.
